Here is a VERY common question.
In the midst/heat of composition, do composers really look for parallel 5ths & octaves, and other voice-leading considerations?
I remember as an undergrad wondering if Bach thought about all of the things we analyzed in class? I was not yet fluent and this was very hard for me, so I didn’t think it was possible.
But the answer is that ABSOLUTELY Bach thought of these things. 100%
How do I know?
Well… after my undergrad years it didn’t take me long to be able to do just that. I was able to follow my creative intuition while effortlessly seeing and adjusting the parallels, voice-leading and voicings. My theory and intuition became this synergistic whole that worked together in concert beautifully, helping each other.
And if I can do it…Bach CERTAINLY was doing it!
How do you get there?
Develop fluency through drills and repetition. Check out this other blog post.
Oh, and shameless plug, take this course “Essential Composer Training : Foundation”. That course was designed with exactly that in mind: to develop skill and fluency so that theory supports intuition.
